[Achievements of tumor surgery in tumors of the liver and bile ducts].

Tumor surgery in this field is no longer such a high risk as previously. Prolonged survival can be achieved by resection of hepatocellular carcinomas in non-cirrhotic livers (3-year survival 58%, n = 54 patients) and for colorectal liver metastases (3-year survival 44%, n = 124 patients). But surgery is rarely successful for the most frequent type of liver malignancy, the hepatocellular carcinoma in cirrhosis. Central bile duct carcinomas are now resected more frequently than in the past. Liver grafting seems indicated in special cases of liver and bile duct tumors. The future developments of operating on the in situ-perfused liver was discussed and the first operation on an ex situ-liver was demonstrated.
